Vascular calcification is a frequent complication in dialysis patients and is strongly associated with mortality. Its pathogenesis is complex and involves a series of markers that act on the vascular microenvironment. There is evidence that aldosterone is one of the biomarkers and may have a role in osteoinductive pathways.The aim of this study was to evaluate the effect of spironolactone, an inhibitor of mineralocorticoid receptor, in the progression of coronary calcification in patients undergoing peritoneal dialysis.
ST elevation myocardial infarction (STEMI) patients affected by multivessels coronary artery stenosis, represent a clinical relevant problem. The management and prognosis of these patents are supported by few literature data. Therefore, in this study authors enrolled real world diabetic vs. non diabetic patients admitted for STEMI and associated to multi vessels coronary disease. Then these diabetics were divided in incretin users (6 months of incretin treatment before study enrollment) vs. never incretin users. In these patients authors studied all cause mortality, cardiac mortality, and major adverse cardiac events at 12 months follow up.
This study will retrospectively review and compare clinical outcomes between left atrial appendage occlusion with dual antiplatelet therapy versus conventional antithrombotic therapy in patients with atrial fibrillation undergoing drug-eluting stent implantation.
The purpose of this study is to determine if the routine use of a sheathless 7F guide catheter for transradial percutaneous coronary intervention (TR PCI) is non-inferior to a 6F sheath/guide combination with regards to radial artery injury (radial artery intimal-medial-adventitial thickening). To evaluate the radial artery, ultrahigh resolution ultrasonography (55 mHz) will be used to accurately quantify radial artery intimal-medial-adventitial thickness (IMT) at baseline and 90 days. A non-inferiority analysis will be performed to compare the degree of radial artery IMT at 90 days between the 7F sheathless guide approach and the 6F sheath/guide combination.
Elective percutaneous coronary intervention (PCI) is often associated with myocardial necrosis evidenced by peri-procedural troponin release. This is a surrogate for subsequent cardiovascular events. There is no study on the effect of peri-PCI oxygenation in in myocardial protection and cardiopulmonary fitness outcome. Patients with higher baseline cardiopulmonary fitness will have lower mortality. This study is to assess the utility of oxygen to reduce ischaemia in patients with significant stable coronary artery disease scheduled for elective PCI. The secondary objective is to evaluate further effect of peri- PCI oxygenation on cardiovascular fitness and autonomic response.
Cardiovascular diseases (CVD) are responsible, throughout the world, for high mortality rates and cardiovascular morbidity. Endothelial dysfunction is the earliest marker of clinical atherosclerosis development. Human studies show that endothelial and microvascular dysfunction are independent predictors of ischemic cardiovascular events and long-term prognosis. The study´s objective is to evaluate the endothelial and peripheral microcirculation changes by venous occlusion plethysmography (VOP), nailfoldvideocapillaroscopy (NVC) and serum biomarkers in patients with myocardial ischemia detected by scintigraphy and normal coronarography.
The aim of our study was to investigate, whether enhancement of left atrial cryoablation by ablation of the autonomic nervous system of left atrium leads to influencing the outcomes of surgical treatment of atrial fibrillation in patients with structural heart disease undergoing open-heart surgery.
A single center cohort which enrolled women who performed mammography, bone densitometry (DEXA), and coronary CT angiography in Seoul National University Bundang Hospital from March 2011 to February 2013.
This is an analysis conducted in the Nurses Health Study and the Health Professional Follow-Up Study, both prospective cohort studies, where the investigators systematically investigated the association between carbohydrate quality using a variety of metrics in relation to coronary heart disease. This was a secondary data analysis of previously collected data in both cohorts.
The purpose of the study is to find out the differential expression profiling of microRNA before and after adiministration of dexmedetomidine in patients undergoing procedures, and then investigators will do some in vitro studies to validate the functions of the microRNA.
